    Blue Sky Energy Solar Boost Charge Controllers

    The Blue Sky Solar Boost charge controllers feature Maximum Power Point Tracking (MPPT), reverse-polarity protection, selectable charge voltage set points, and an equalize function. An optional user-friendly digital display is available to monitor PV charge performance. The display shows battery voltage, solar current, charge current, and charge mode, either in the controller, as a remote panel installed up to 300' away, or both. Optional temperature sensor provides for compensation of charge voltage to further improve charge controller and battery performance. Solar Boost controllers are available with or without the digital display and optional remote display. 5-year limited warranty.

    Solar Boost 2512i-HV

    Patented Maximum Power Point Tracking technology allows Solar Boost 2512i-HV and 2512iX-HV to increase charge current up to 30% or more compared to conventional charge controllers. The new higher input voltage capability of the HV version product now allows the use of higher voltage lower cost 60 cell PV modules to charge a 12 volt battery. Don’t waste your money by throwing PV power away! Get the power you paid for with a Solar Boost charge controller.

    The lower cost Solar Boost 2512i-HV provides an advanced fully automatic 3-stage charge control system to ensure the battery is properly and fully charged, resulting in enhanced battery performance with less maintenance. A partial IPN™ network interface is also included to allow use of the Universal Communication Module (UCM), and IPN-Remote and IPN-ProRemote displays.

  • 20/25 Amp 12 Volt Rating Supports A Wide Range Of Applications
  • Optional IPN-ProRemote Display Provides Charge Control & Full-Featured Battery Monitoring System
  • Supports up to 270W of 60 Cell modules
  • 3-Stage Charge Control with Filtered PWM Output Improves Battery Performance & Life While Minimizing Battery Maintenance
  • Clear Anodized Faceplate, Conformal Coated Electronics & Plastic Case Resist Corrosion
